bombogenesis

noun

1. (uncountable)Rapid or extreme cyclogenesis, often characterized by a barometric pressure drop of 24 millibars in a 24 hour period.

   “Bombogenesis: A colloquial term for sudden, extremely rapid almost explosive intensification of low pressure systems just off the Atlantic Coast of the United States.”

   “The storm intensified from 990 mb to 956 mb in just 12 hours Sunday morning, a drop of 35 mb. Another case, like “Nemo”, of bombogenesis.”

   “Experts say the storm will undergo bombogenesis, meaning that colder air is expected to mix with warmer sea air, leading to a swift drop in atmospheric pressure. The process leads to a so-called bomb cyclone.”

   “As the area where the two air masses meet, called the Arctic front, moves northward and eastward, conditions for bombogenesis should continue moving as well, Mr. Moore said.”
